WINDOW-LOCKING MEANS.

Specification of Letters Patent.

Patented Jan. 9, 1906.

Application filed August 9, 1905. Serial No. 273,325.

o all whom it may concern,.-

Be it known that I, THOMAS LEE, a citizen of the United States, residing at Home City, Hamilton county, State of Ohio, haveinvented certain new and useful Improvements in l/Vindow-Locking Means; and I do declare the following to be a clear, full, and exact description of the invention, attention being called to the accompanying drawings, with the reference characters marked thereon, which form also a part of this specification.

This invention relates to devices for locking a swinging structure, like a sash, window, door, or transom, in its closed position.

The invention contemplates the provision of two catches at opposite sides of such a window and of means for manipulating them simultaneously.

The invention consists of the particular arrangement of these two catches, of the means for manipulating them simultaneously, and of certain features of construction relating particularly to one of the catches.

In the following specification, and particularly pointed out in the claims at the end thereof, is found a full description of my invention, together with its operation, parts,

and construction, which latter is also illustrated in the accompanying drawings, in which- Figure 1 is a sectional side view of a window, showing the same in its closed position, held so by two catches, its open position being shown in dotted lines. Fig. 2 is part of a front view of Fig. 1, showing particularly the locking-catches. Fig. 3 is an enlarged side view of the upper catch, partly in section. Fig. 4 is a rear view of the same as it appears when detached. Fig. 5 is an enlarged top view of the lower catch.

vA indicates a certain structure, which may be a door, transom, sash, or window, which is pivotally supported at c on opposite sides, so that it may be swung from one position into another one-that is, from a closed one, as shown in Fig. 1, into an open one, as shown in dotted lines in same figure, or vice versa. The particular construction of this structure, which will be referred to hereinafter as a window,77 or of the parts 0r frame surrounding it, has no bearing on my invention. Catches are provided, one on each of the opposite free or swinging sides of this window, preferably in the center of these sides and at points opposite each other. In the position of the window as shown B would be the catch at the upper side, and C the catch at the lower side, of the window, the latter catch being in a vertical line below the former, as best shown in Fig. 2. Both are gravitycatches-that is, they have a normal tendency to drop in locking position by action of their weight. The upper catch consists substantially of a bolt 10, supported so as to have a sliding movement in a housing 11, which is provided with ianges 12 for-attachment. The bolt has a slot 13, into which reaches through an"opening 14 in the front of the housing the inner reduced end of a weighted lever 15, pivotally supported on pivot-pins 16, which occupy openings 17 in opposite sides of housing 11. The arrangement of all these parts is such that lever 15 holds bolt 10 normally in engagement with its keeper 18, which is provided in proper position on the surrounding frame and opposite the upper edge of the window. The movement of this bolt 10 may be limited by keeper 18 or by limiting the movement of lever 15 by means of arranging the length of opening 14 accordingly or by providing shoulders 19, adapted to come in contact with the upper and lower ends of the housing-and which are obtained by increasing the width of a part of the bolt within the housing, as best shown in Fig. 4. For unlocking this catch a pull 21 is provided, which is attached to the lower end of the bolt, the manipulation being as indicated in dotted lines in Fig. 1. The lower catch is substantially in form of a weighted hook 22, pivotally supported in bearings 23, which are attached near the lower edge of the window. The shape, arrangement, and position of this hook 22 is such.

that when the window is closed it normally drops into locking engagement with its keeper 24, as best shown in Fig. 1. To provide for the simultaneous unlocking of these two catches B and C, I use a link which connects them, so that when the upper catch is unlocked by means of pull 21 the lower one is also unlocked. For such purpose I use, preferably, a rod 25, which connects weighted lever 15 and hook 22, as illustrated, so that when this lever rises, as shown in dotted lines in Fig. 1, it also lifts hook 22 out of its keeper 24. After so unlocked pull 21 may also be used to swing the window open by pulling in proper direction. (Note dotted lines in Fig.

1.) After the window is open it may also be held so by means of this pull by hooking the ring at its lower end into a hook 26 below the window. This hook is pivotally attached so IOO IIO

as not to project when not used. These closing means are well adapted for use in connectionwith so-called fiile-resisting windows, which consist of sheet-metal frames closed by panes of wire glass. Such windows are mostly provided with means operating automatically for the purpose of closing them in case of a tire. The operation ot' such means is usually based upon the destruction of a connection by a certain temperature. Fusible links are generally used for this purpose, and in case my window-closing means are to be used in connection with such windows such a fusiblelink may be provided on pull 21 and as shown at 27.

When the open window is released and swings into closed position, the catches (bolt 10 and hook 22) lock automatically as soon as they come in Contact with their keepers. The movement of the catches is limited in a manner to insure such contact. The means for limiting the movements of bolt 1() have been described. Hook 22 is prevented from dropping below a proper position by an extension 28 below its pivotal support.

Openings 17 need to be merely sufliciently large to admit pivot-pins 16. They are shown in form of slots, however, and rearwardly open (see F1g. L1) to permit convenient assembling of the parts, which they do by permitting insertion of lever 15 with its pins 16 as a whole, said pins-forming lateral projections on this lever. It is obvious that the upper catch may also be used independently of an additional lower catch.

Having described my invention, I claim as newl. In combination with a window, an upper window-locking catch consisting of a bolt, a keeper for it, a weighted lever to hold this bolt normally in locking engagement with its keeper, a lower window-locking catch, a link connecting it with the weighted lever ofv the upper catch and means to manipulate this latter to unlock it and simultaneously also the lower catch.

2. In combination with a window, a locking-bolt at its upper edge, a keeper for it, a weighted lever to hold it normally in locking engagement with its keeper, a weighted hook at the lower edge of the window, a keeper for it, a link to connect this hook with the weighted level' ot' the upper catch and means to manipulate this latter.

.In testimony whereof I hereunto aiiix my signature in the presence of two witnesses.

THOMAS LEE.
